It is possible to use LABEL=... and UUID=... in fstab, mount understands them, but quota do not. I made a quota package version with the following changes: - updated to quota 1.70 - fixed small error in setquota.c (new in 1.70) - added LABEL and UUID support. The are both recognized by the programs and may be used as arguments. E.g. some fs may be referenced as LABEL=WWW (partition was labeled so and this is used in fstab) or /i (mount point) or /dev/sdi1 (real name, translated via mtab or /proc/mounts if there is no mtab) The packages (src and sparc RPMs) are available in ftp://sunsite.icm.edu.pl/private/rzm/quota/ I hope they will be useful.
Red Hat Linux 7 and later support UUID/LABEL.
