This page is about Debian GNU/kFreeBSD Live CD.

Feasibility

We would like to have a Debian GNU/kFreeBSD Live CD but in order to have that we need to check the feasibility of it.

FreeBSD Live CD(s)

kFreeBSD live-build requirements

Overlaying filesystem support

  • UnionFS
    • For Linux live-build uses UnionFS.
    • On kFreeBSD UnionFS exists and works (with small issue where a changed file is listed twice in directory listing (plus "sometimes" an additional file of the same filename but appended with tilda (~)) but "ls"ing the file results only in one result).

# mount -t unionfs -o noatime /mnt/ /media/cdrom
# mount | grep /media/cdrom
/dev/cd0 on /media/cdrom (cd9660, local, read-only)
<above>:/mnt on /media/cdrom (unionfs, local, noatime)

# ls /media/cdrom/
