(the e2fsprogs directory is too twisty and evil to easily fix, but I plan to rewrite it anyway so I'll just bump that up in priority a bit).

2003-12-19Patch from Fillod Stephane:Eric Andersen
You will find in the attached file "syslog.patch" a patch which adds config options to set at compile time the size of the circular buffer, and some documentation update.
2003-09-26Patch from Fillod Stephane Glenn L McGrath
Add follow mode to logread, ala "tail -f /var/log/messages" Note: output to a slow serial terminal can have side effects on syslog because of the semaphore. In such case, define RC_LOGREAD.
