I will not get into why, but I executed a git built for 1400082
in a 1400081 world context and got what was to me a surprise,
given that /lib/libc.so.7 is part of 13.2-RELEASE :
ld-elf.so.1: /usr/local/bin/git: Undefined symbol "__libc_start1@FBSD_1.7"
Does this mean that a /lib/libc.so.8 is pending? Or do the
criteria for the likes of /lib/libc.so.7 allow for new
symbols over time without a name change, even after a
release contains a /lib/libc.so.7 ?
Just curious about the criteria. Executing newer on older is
not my normal type of activity: usually avoided.
FYI: Checking 13.2-RELEASE shows it is using /lib/libc.so.7 :
