Daniel Barlow 0173a9ced9 set PATH correctly in ssh sessions 
for a non=interactive shell ("ssh linminix foo") ash does not source
*any* startup files, so we need to set this to something more useful
than /bin:usr/bin

Daniel Barlow b0098f1c8e move min-list-garbage into min-collect-garbage pkg

Daniel Barlow 00aeb81811 min-list-garbage: check all store paths against file 
this is step 1 of min-collect-garbage, no point implementing
deletion ourselves when rm -r exists

(arguably no point in implementing any of it, but this is the bit we
can't do efficiently in bourne shell - it means we're reading the
store-paths list once instead of grepping it afresh for every entry in
/nix/store/)

Daniel Barlow b1f4db00a0 add liminix-rebuild command 2023-05-17 15:38:22 +01:00
Daniel Barlow b0a0fdcfcc add "standard" module, which includes flashimage kexec & jffs2 
most systems need most of these, so it makes writing the docs a
lot easier

Daniel Barlow 888a0d5f74 mips-vm: allow env var to override la network interface 
this is handy if you want to connect to it from the host
for e.g. seeing if min-copy-closure works

Daniel Barlow 4cfaed7303 specify root device as /dev/mtdblockn 
the (openwrt?) magic that autodetects it based on mtd labels
won't work with a two-stage boot
 2023-04-26 22:16:15 +01:00
Daniel Barlow 6d6dbe1cbb tftpboot: allow padding image with freeSpaceBytes 
this is useful for writable filesystems so that there's more than
an erase block of space to write into

Daniel Barlow 2c4f8b823e remove jffs2boot target 
It's not needed now initramfs is compiled into the kernel.
 2023-04-23 20:56:20 +01:00
Daniel Barlow 3595e36294 workaround for huge musl binaries 
something in our configuration is causing gcc to generate binaries
in excess of 68K for "hello world". hardeningDisable seems to stop it
doing that, turning it on for s6 which writes _lots_ of binaries
but would be good to get to the bottom of this

Daniel Barlow 65dfbad365 systemconfig: chown files if uid/gid > 0 2023-04-15 22:53:28 +01:00
Daniel Barlow 5dd0c6e3c0 rewrite preinit as very small C program 
By using the kernel "nolibc" header to avoid requiring a C library, we
can bring the initramfs size to around 4k

This does involve a tiny bit of inline mips assembly which I'm not
sure about. gcc seems unwilling to generate the code to load $gp at
function entry of main(), so we do it by hand - but I'd rather find
out why gcc doesn't.

Daniel Barlow 1cc0b13b57 rewrite systemconfig in C and link statically 
systemconfig (a.k.a "activate") is run from the initramfs. Converting
it from a shell script to an executable means it doesn't depend on
there being a shell in the initramfs
 2023-04-15 17:21:27 +01:00
Daniel Barlow c744ef8c17 systemconfig: accept uid and gid options 
all we do with them is assert they're zero, to unbreak CI.

this doesn't matter for qemu, but there's no other way of
