#BK updated 20,22 sept 2007 v2.22, multisession bugfix.
#v3.01 BK 10 oct 2007, attempted bugfixes for funny CD drive.
#v3.01 BK 11 oct 2007, removed multisavefunc() to functions4puppy.
#v3.02 BK 1 nov 2007, can change folder of pup_save file.
#v3.97 BK feb 2008: restore support for pcmcia-cs package.
#v3.97 BK 5 mar 2008, handle PSAVEMARK, see /etc/rc.d/PUPSTATE, init script.
#REMOVEDv3.98 BK 2 apr 2008: 'mke2fs -O none' for encrypted pup_save, fix mntg bug.
#v3.99 7apr2008: fix zombie process prevents partition unmount.
#v411 run rc.alsa as it also unloads modules (if not done, prevents shutdown some systems).
#v411 bring down network interfaces, as sometimes prevent poweroff.
#v412 /etc/DISTRO_SPECS, renamed pup_xxx.sfs, pup_save.2fs etc.
#w002 pup files renamed to format upup-555.sfs, upupsave.2fs.
#w468 alsa shutdown now handled in /etc/init.d/alsa.
#w481 if low-ram, save-file is on a fast media, and no swap file/partition, then create swapfile.
#w482 use xorriso instead of cdrtools/cdrkit if installed.
#v431 tulindo: fix saving to ext4 partition.
#091117 weird shutdown bug. would not shutdown when a partition mounted, x restarted.
#091222 added support for saving to /dev/mmcblk* devices.
#100107 would not shutdown if ntfs partition mounted. Added timeout in shutdown dlg.
#100301 brought code to stop network interfaces further down, also consider 'defaultconnect'.
#100309 network shutdown improvement.
#100315 improper shutdown f.s. check.
#100401 choose ext2/3/4 for pupsave file. 100410 offer ext2/3 only.
#100604 shel: Unload the Ethernet drivers on shutdown to prevent battery drain.
#100615 Patriot: suggested code to enable save-layer to remount ro.
#100719 cannot save session to entire partition if puppy installed in a subdirectory.
#100814 log the cumulative bytes transmitted on network.
#100820 delete /var/tmp/* (apparently filled by opera crashes).
#100902 rerwin: log the cumulative bytes transmitted on dialup.
#100911 fsckme.err filename changed to fsckme.flg. see also initNEW, rc.sysinit, init (initramfs).
#100912 no longer have FASTPARTS variable in /etc/rc.d/PUPSTATE, use ATADRIVES instead.
#100912 if copy .sfs's from cd to hd, copy into a subdir, DISTRO_IDSTRING truncated to 8 chars.
#100915 booting cd, put save-file in same subdir (as 100912).
#100917 booting usb, if drive has more than one partition, allow choice where save session.
#100920 reverse 100915. Fix SAVEPATH.
#100926 crap, recent versions of dialog do not work with --ok-label, --cancel-label, if no extra button...
#101013 dir name to be 8+3 chars ex w0901010.083 (<fileprefix1stchar><version><year><month>.<day><kernel3rdchar>)
#101020 if pup installed in a sub-directory, allow save-file in another partition (in same drive).
#101211 shinobar: bugfix.
#110217 bad hack, see /etc/rc.d/rc.update.
#110405 fix 'free' applet output format different in later versions of busybox.

#110430 added warning multisession does not work with laptop optical drives. changed dlg timeout from 60 to 90.
#110503 set owner/permission of dirs when 1st save. this is important when choose to run as fido on 1st shutdown.
#110524 notice not to choose fido, as experimental status only.
#110808 L18L: if geany still running at shutdown, delete socket.
#110919 test for usb interface invalid for kernel with inbuilt usb drivers.
#110919 moved creation of save-file code to /usr/sbin/shutdownconfig.
#110919 unlock rfkill. jemimah has this in fluppy. if don't do this, may be locked at next boot.
#v2.20b make shutdown less verbose...
#110923 L18L: i18n conversion. please see /usr/share/doc/nls/shutdownconfig
#110928 fixed, reboots when choose shutdown. very old bug, dates back to 2009.
#110928 modified i18n conversion, only for echo to /dev/console.
#111106 do not execute fuser if network share mount.

#120130 rodin.s: update for gettext (line 91).
#120218 changed TEXTDOMAIN=etcrcd___rc.shutdown to TEXTDOMAIN=rc.shutdown (unlikely to be any other file same name in $PATH).

#120409 experimenting with minit, i discovered "rm -rf /tmp/*" is killing mingetty. initrd.gz wipes it, have added code to wipe for full hd install at bootup...
#120427 01micko: support ext4 save-file.
#120514 WARNING: i don't have this problem, as no longer deleting /tmp/* (120409), however Karl Godt reported that 'fuser -k -m' may kill rc.shutdown then if no /tmp/bootcnt.txt then X restarts, ref: http://bkhome.org/blog/?viewDetailed=02827
#120514 Karl Godt: 1st shutdown: test save-file mounted rw, not ro. 120522 removed.
#120514 shinobar: avoid killing this script.
#120522 precise puppy with aufs, have two dirs .wh..wh.orph, .wh..wh.plnk, in /initrd/pup_rw, filter out.
#120629 raspberry pi does not have a hw clock. save date here, read at bootup (see rc.country).
#121104 saving to entire partition, must save /var/local. fixed some text translations.
#121104 move some code up, to before saving session, as some files were not getting saved in some PUPMODEs.
#121104 official 'fuser' output format changed, when save to entire partiton 'fuser' kills too much prevents shutdown.
#121125 umount is a script, this line also unmounts ntfs partition (if mounted) -- which is a bug in script -- use umount-FULL.
