grep and libpcre3
On m68k, /bin/grep needs /usr/lib/libpcre.so.3, which may not be available
early in the boot process, causing many error messages during boot up (/usr is
a separate partition on my box):
| cassandra:~# type -all grep
| grep is /bin/grep
| cassandra:~# ldd /bin/grep
| libpcre.so.3 => /usr/lib/libpcre.so.3 (0xc0018000)
| libc.so.6 => /lib/libc.so.6 (0xc0026000)
| /lib/ld.so.1 => /lib/ld.so.1 (0xc0000000)
| cassandra:~# dpkg -s grep
| Package: grep

| Installed-Size: 628
| Maintainer: Ryan M. Golbeck <rmgolbeck@debian.org>

| Conflicts: rgrep
| Description: GNU grep, egrep and fgrep
| 'grep' is a utility to search for text in files; it can be used from the
| command line or in scripts. Even if you don't want to use it, other packages
| on your system probably will.
| .
| The GNU family of grep utilities may be the "fastest grep in the west".
| GNU grep is based on a fast lazy-state deterministic matcher (about
| twice as fast as stock Unix egrep) hybridized with a Boyer-Moore-Gosper
| search for a fixed string that eliminates impossible text from being
| considered by the full regexp matcher without necessarily having to
| look at every character. The result is typically many times faster
| than Unix grep or egrep. (Regular expressions containing backreferencing
| will run more slowly, however.)
However, on PPC I have the exact same package version, and grep doesn't depend
on libpcre3 there:
| geert@callisto:~$ ldd /bin/grep
| libc.so.6 => /lib/libc.so.6 (0x0fea2000)
| /lib/ld.so.1 => /lib/ld.so.1 (0x30000000)
| geert@callisto:~$ dpkg -s grep

Is there any (good) reason for this? Shall I just file a bug on the m68k
package (programs in /bin must not rely on libraries outside /lib)?
Apart from that, everything seems to be fine. My poor Amiga has been working
hard to upgrade to testing during the last 2 weeks (it takes some manual
playing with apt-get install if you don't want to let dist-upgrade remove some
important packages), and it's almost there ;-) And all done while running
2.6.5-rc2, so I think 2.6 is getting stable.
