Using the boot-pao.flp for 2.2.5-RELEASE, I observed the following:
When repeatedly trying the installation and kernel recompile procedures,
the kernel customization fails:
config takes several minutes instead of about 15s.
make depend takes several minutes instead of about 30s
or even stops with "out of memory".
make takes up to 40 minutes instead of 8min
and stops with "Memory exhausted" or "Out of swap space".
I believe the reason for this is related to "inflated" files that I
found. Some step (which?) seems to append them rather then replacing
them when the installation is repeated, making them multiple copies of
themselves. Among others, those files were:
/usr/src/sys/i386/isa/ic/i82593.h
/usr/src/sys/i386/isa/if_snreg.h
/usr/src/sys/i386/isa/if_wl_i82586.h
/usr/src/sys/i386/scsi/ncr53c500/ncr53c500if.h
/usr/src/sys/i386/scsi/scsi_low/scsi_low_if.h
/usr/src/sys/i386/scsi/tmc18c30/tmc18c30if.h
/usr/src/sys/pccard/pccard_subr.c
/usr/src/sys/pccard/cardbus.h
When this occured, I found my way out with the following clearcut
method.
If using /stand/sysinstall, Alt-F4 into shell
backup configuration file original and formerly used customization
/usr/src/sys/i386/conf/MYPAO ->
/usr/src/sys/i386/conf/MYPAO.BUP
/usr/src/sys/i386/conf/PAO -> /usr/src/sys/i386/conf/PAO.BUP
inside /usr/src/sys, remove everything except
/usr/src/sys/i386/conf/LINT
/usr/src/sys/i386/conf/MYPAO.BUP
/usr/src/sys/i386/conf/PAO.BUP
/usr/src/sys/compile
install generic kernel again, including kernel sources
do manual PAO kernel customization
