We already change UT_NAMESIZE, lets change UT_HOSTSIZE in the same round :-) Usually bigger UT_HOSTSIZE gives much better statistics, because too many of hosts now exceedes 16 char limit. > ut_hostid (normally an in_addr type of entry so that we can always find the > originating host without having to bogusly interpret or convert > ut_host to/from hostnames and dotted-quad IP addresses.) Yes, it will be nice to have. Many systems already have it. > ut_host (increased to pad out the record size to a convenient power of 2) IMHO even 32 isn't enough now, we need at least 64 > I don't see a mirror image of the BSDI file format as particularly > important, in all my travels, I've never seen an application (read: > non-system) binary that uses the utmp file, except on my SVR3 days.
