NodeOS initramfs
This package generate a initramfs image that will try to mount the users
filesystem, set on the root=
flag on Linux command line. If it fails to do so,
it boots to a Node.js REPL prompt using an
on-memory root filesystem.
Note about env.js
Since /usr/bin/env
is also a Node.js script, to use less memory and boot
faster it's checking that the script to be run is already a Node.js script and
if so, it require()
s it and exec it directly to re-use the current Node.js
instance. This has the drawback that Python-inspired tricks like
!module.parent
or require.main === module
will not work anymore. A better
alternative and currently more widely used when a package can be used both as a
library and as an executable is to define the executable at an independent
script file and use the package.json
main and bin entries.
