Mount name length limit (MNAMELEN)

Wed Aug 4 07:40:20 PDT 2004

Hi

It seems that the constant is in /usr/sys/sys/mount.h.
The limit is already there since the initial import in
1995. (From 4.4BSD?)
I want to know what is the root cause preventing a
larger value.

PS: I have found some interesting links about
MNAMELEN:

that Tru64 UNIX also have a restriction of 90
chars.(They also based on BSD?)
