From 6d2832ebae620952e56fbb8e628ba4f3be64cc2c Mon Sep 17 00:00:00 2001 From: Eric Hameleers Date: Fri, 24 Jun 2016 23:30:02 +0200 Subject: iso2usb.sh: make the name of the '/home' LUKS container configurable. New parameter to the script: -l|--lukshome Custom path to the containerfile for your LUKS encrypted /home (slhome by default). Note: not only (just as with the persistence container) can you choose a custom name for the the LUKS container file but you can also create it in a subdirectory instead of in the filesystem root now. --- iso2usb.sh | 62 ++++++++++++++++++++++++++++++++++++++++++++------------------ 1 file changed, 44 insertions(+), 18 deletions(-) (limited to 'iso2usb.sh') diff --git a/iso2usb.sh b/iso2usb.sh index 11c9605..e0aa770 100644 --- a/iso2usb.sh +++ b/iso2usb.sh @@ -26,6 +26,10 @@ set -e # Set to '1' if you want to ignore all warnings: FORCE=0 +# By default, we use 'slhome.img' as the name of the LUKS home containerfile. +DEF_SLHOME="slhome" +SLHOME="${DEF_SLHOME}" + # By default, we use 'persistence' as the name of the persistence directory, # or 'persistence.img' as the name of the persistence container: DEF_PERSISTENCE="persistence" @@ -66,6 +70,7 @@ IMGDIR="" ISOMNT="" CNTMNT="" USBMNT="" +US2MNT="" # Compressor used on the initrd ("gzip" or "xz --check=crc32"); # Note that the kernel's XZ decompressor does not understand CRC64: @@ -93,6 +98,7 @@ cleanup() { [ -n "${ISOMNT}" ] && ( /sbin/umount -f ${ISOMNT} 2>/dev/null; rmdir $ISOMNT ) [ -n "${CNTMNT}" ] && ( /sbin/umount -f ${CNTMNT} 2>/dev/null; rmdir $CNTMNT ) [ -n "${USBMNT}" ] && ( /sbin/umount -f ${USBMNT} 2>/dev/null; rmdir $USBMNT ) + [ -n "${US2MNT}" ] && ( /sbin/umount -f ${US2MNT} 2>/dev/null; rmdir $US2MNT ) [ -n "${IMGDIR}" ] && ( rm -rf $IMGDIR ) set -e } @@ -116,8 +122,11 @@ cat < Full path to the ISO image file. +# -l|--lukshome Custom path to the containerfile for your LUKS +# encrypted /home ($SLHOME by default). # -o|--outdev The device name of your USB drive. -# -p|--persistence Custom name of the 'persistence' directory. +# -p|--persistence Custom path to the 'persistence' directory +# or containerfile ($PERSISTENCE by default). # -r|--refresh Refresh the USB stick with the ISO content. # No formatting, do not touch user content. # -u|--unattended Do not ask any questions. @@ -184,15 +193,19 @@ update_initrd() { if [ $REFRESH -eq 1 ]; then echo "--- Refreshing Slackware initrd..."
