At end of upgrade install (when X shuts down), a message was displayed on the console to the effect of "Error writing /boot/map - no free space". After rebooting, the system only displayed "LI" when trying to load LILO. The installer had previously complained that there was not enough space on /boot to install the kernel, so I freed up 3 megabytes (of 7 megabytes total). The installer apparently does not ensure that there is enough space on /boot to execute lilo properly. The system is i686 SMP, AIC7890U2W SCSI, and was originally running RedHat 6.1.
I've tried to reproduce this problem - I created a /boot and filled it up and only left a few hundred K free. The installer properly caught there was not enough free space. I am going to defer this issue for now and see if more reports come in to help us understand the failure mode.
Can somebody explain to me (a total newby) how I work around this problem, and get a successful install on machines that have this problem. Thanks- -EAB
