Solved Building mfsBSD using FreeBSD 15.0

[balanga]

I encountered it earlier and the hack still works. Make a variable and insert it in script.

Post in thread 'What is minimum RAM size you would consider for MFS build???'

I need to increase the mfsroot size next go around.

Well this was easier said than done. There is no room left on any of the usb+mfs builds.
I hacked in a variable to let me set it.
${MFSROOTSIZE}
/usr/local/share/poudriere/image_mfs.sh

MFSROOTSIZE=800m

_mfs_create()
{

        cat >> ${WRKDIR}/world/etc/fstab <<-EOF
        /dev/ufs/${IMAGENAME} / ufs rw 0 0
        tmpfs /tmp tmpfs rw,mode=1777 0 0
        EOF
        makefs -s${MFSROOTSIZE} -B little -o label=${IMAGENAME} ${WRKDIR}/out/mfsroot ${WRKDIR}/world >/dev/null 2>&1
}

SNIP

When I run poudriere image for...

• Phishfry

MFSROOTSIZE=800m

makefs -s${MFSROOTSIZE} -B little -o label=${IMAGENAME} ${WRKDIR}/out/mfsroot ${WRKDIR}/world >/dev/null 2>&1

Then I get a working image:
poudriere image -t usb+mfs -s 960m -j mbm-mfs -h mbm-mfs -n mbm-mfs -X excluded.files

Next up create an OVERLAY directory to add my files in.

Any tips on how to do this?

One thing I would like do is use zsh as my shell because I use mc a lot

Same here. My descision was to stick on the default shell for root for maximum compatibility. As a result mc doesn't start without -u. Lazy as i am i set an alias in /root/.shrc and later i found out how to use tcsh with mc only. This is my /root/.shrc now:

echo ".shrc loaded"
#alias mc="mc -u"
alias mc="env SHELL=/bin/tcsh mc"

I'm pretty sure that this will work with zsh if you found its root dotfile. Create inside mfsbsd a customfiles/root/ , copy your dotfile into it and make your mfsBSD. The customfiles/ files are included into the image on the fly without setting parameters for the make command. (No CUSTOM=1 required, thats for building custom kernels. Ouch, learning by doing.)
