What exactly do you think by 'not covered'? That the hardlink hierarchy is not maintained during the update?
Yes. Given the extent to which various unchanged config files in the /etc tree get new timestamps when various package updates occur, it would not surprise me, hence the question. What bothers me more is absent using a hardlink between the two, HOSTNAME gets a new create date when hostname gets "created" via mv to HOSTNAME. If it was up to me, the update process would hard link instead of moving, creating a soft link, and leaving behind litter in the form of an .rpmsave or .rpmnew. Better still would be to do no more than a rename, period, dispensing with the HOSTNAME that is pointlessly unique among major distros to openSUSE/SLEx. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
