Public bug reported: I have a probably unusual setup in a VM where I need to luksOpen 3 disks during boot (I'm using ZFS raidz1 on 3 luks-encrypted disks).
""" During boot, I get a rather puzzling error: error: can't find command f94f182a584c4b40bf6d error: can't find command 82fae0edbdc74b938550 Press any key to continue... """ The generated grub.cfg file explains it. It has this bit repeated all over the place: (...) cryptomount -u 3c26d0e32abf412a8b5ea1f837bf9346 f94f182a584c4b40bf6d93d04990a02a 82fae0edbdc74b9385502c6a8db496ba (...) That should actually be 3 cryptomount -u lines, not just one. I tracked it down to grub-mkconfig_lib in this bit of code: if [ x$GRUB_ENABLE_CRYPTODISK = xy ]; then for uuid in "`"${grub_probe}" --device $@ --target=cryptodisk_uuid`"; do echo "cryptomount -u $uuid" done fi For some reason, the IFS this code is using isn't working to parse the output of grub_probe. I ran the command manually in my shell, and it looks fine: # /usr/sbin/grub-probe --device /dev/mapper/crypt1 /dev/mapper/crypt2 /dev/mapper/crypt3 --target=cryptodisk_uuid 3c26d0e32abf412a8b5ea1f837bf9346 f94f182a584c4b40bf6d93d04990a02a 82fae0edbdc74b9385502c6a8db496ba I made a few attempts at different values of IFS, but couldn't get it to correctly use one cryptomount line per uuid. It must be something simple, but I couldn't figure it out, sorry. This doesn't prevent my system from booting, I just have to press ENTER when it errors like that, or wait a few seconds. Since I have to be at the console anyway to type the passphrases, it's not a blocker, just an annoyance.
