dedicated mini-strata


It is possible to have a sort of mini-strata? What I mean is, a strata that includes one program and only the needed libraries for that program.

Yes, it works fine. If you statically compile the executable so it does not need other libraries you can have a stratum that is (effectively - not actually, see below) a single file. You can also have strata without any executables. For example, you could have a stratum that is just man pages or icons. Applications provided by other strata which use those man pages or icons would then pick them up automatically.

When you enable strata Bedrock Linux creates some files and directories to ensure cross-stratum coordination. For example, /proc and /dev. So once you enable such a mini-stratum you'll end up with more files than strictly the executable-with-libraries you've proposed, but not meaningfully so.

If you want to experiment with this, it's worth noting that the current release of Bedrock Linux as of time of writing - 1.0beta2 Nyla - provides a statically compiled busybox at /bedrock/libexec/busybox. You should be able to make a mini-stratum with just this. It'd be something like:

Code:
# make stratum's files
mkdir -p /bedrock/strata/mini-stratum-test/bin/
cp /bedrock/libexec/busybox /bedrock/strata/mini-stratum-test/bin/
# make config
printf "\n[mini-stratum-test]\nframework = default\n" >> /bedrock/etc/strata.conf
# enable stratum for use
brs enable mini-stratum-test
# test
brc mini-stratum-test busybox --help

Whoa. That is very cool. It opens up possibilities, yes it does.

Understood.

That is extremely cool! I've been reading about busybox & toybox for a while and have found the concept fascinating.

Thank you for the information.
