hey all,
so i just upgraded this morning from snv_105 to snv_106. now
Install(1M) is hanging whenever i run it. i'm wondering if anyone else
has seen this problem. (perhaps there's already a bug filed?)
i'm running it as follows:
Install -o debug -k i86xpv -T domu-219:/tmp
and here's where it's hung:

there is only one place where Install(1M) invokes "uniq":
set -- `grep "^CONF" $modlist | sort | uniq`;
as it turns out, i can easily reproduce this problem as follows:
---8<---
e...@mcescher$ ksh93
e...@mcescher$ set -- `cat /etc/termcap | sort | uniq`
<hang>
---8<---
