Maybe it's bad netiquette to dump the code in an email. I'll put it at the
end to reduce the pain. It's not too long. Seems to me it's just a bunch of
regex tests but you're correct, it doesn't look to test if the device
actually exists, merely that the parameter is valid/as expected.
I'm going to evolve this question slightly - where is the official upstream
code for clonezilla? Website is a bit unclear. Maybe some website updates
are in order on how people can fork the repo(s), see the code, offer PRs,
etc. Something to think about.
Shell Code:
```
is_partition() {
# //NOTE// If new RE* is added, remember to check the function
check_if_disk_busy_before_create_partition and get_not_busy_disks_or_parts
have to be modified, too.
# IDE and SCSI disk partition: /dev/hda1, /dev/hdb1, /dev/sda1,
/dev/sdb1...
# KVM virtual disk partition: /dev/vda1, /dev/vdb1...
# Xen virtual disk partition: /dev/xvda1, /dev/xvdb1, /dev/xdvc1...
# CCISS RAID disk partition: /dev/cciss/c0d0p1, /dev/cciss/c0d1p1...
# SD card: /dev/mmcblk0p1, /dev/mmcblk0p2, /dev/mmcblk0p3...
# NBD device: /dev/nbd0p1, /dev/nbd0p2...
# NVME device: /dev/nvme0n1p1, /dev/nvme0n1p2, /dev/nvme1n1p1,
/dev/nvme1n1p2
# FakeRAID: with nodmraid boot parameter, /dev/md126p1, /dev/md126p2...
# Mylex ExtremeRAID-2000 SCSI RAID controller: /dev/rd/c0d0p1,
