#v411 update what gets copied from /root and /etc.
#v412 /etc/DISTRO_SPECS, renamed pup_xxx.sfs, pup_save.2fs etc.
# 22jun09 by Masaki Shinomiya <shino@pos.to> bugfix in cd drive selection
# 01jul09 needed space calculation
# 08jul09 loop mounted iso file usable
# 7aug09 grub4dos support
#w482 shinobar: exclude /lib/modules/${KERNELVER}/initrd.
#v431JP mkisofs with Joliet option, volume id, what copied from cd, remove slmodems
#091212 weird bug, no processes but when run this, x restarts...
# 28dec09 remove /modules/${KERNELVER}/modules.*
#110505 support sudo for non-root user.
#110808 PANZERKOPF: bug fix. 110822 reverted.
#120605 rerwin: omit /dev/snd content, /dev/.udev subdirectory and modem daemons from new master (because daemons reinstalled from firmware if needed).
#120606 rerwin: support users' replacement of stripped /root & /etc with complete directories (for "boot disk").
#120607 rerwin: Remove indicators/files for integrated user-installed packages.
#120721 revert 'wildcards' option (from 120605); improve /dev/snd file exclusion; exclude /usr/share/icons/hicolor/icon-theme.cache (shinobar).
#121021 rerwin: revert 120605 modem daemon removals (because daemons no longer copied from firmware directory).
#130222 convert internationalization from "technosaurus method" to gettext method.
#130222 virtual-CD detection was broken.
#130223 various fixes. note, also fixed /usr/sbin/filemnt. now can retain files between remasters.
#130301 o/p of "losetup" (BB), shows all in use, but "losetup-FULL -a" needs param, also o/p format different.
#130302 L18L: moved m_09 m_10 m_11 top and made another use of it.
#130306 gettext translation fixed, line 354. 130307 again.
#130308 npierce: filter out wrong CDs from choices offered to user; remove CD drive from VIRTUALCD list.
#130527 /etc/.XLOADED has been moved to /root, refer /usr/bin/xwin.
