1 year ago Hi!
As this works perfectly on my laptop, I am pretty sure this is an issue with iSH.
Maybe tbodt himself may look into this, as this is a system call problem?
Thanks a lot and please let me know if I can help :-).
Kind regards, Maurice

Hi iSH team!
Some of my nodejs apps are failing on iSH because of a bug in system call copyfile (see below).
Could somebody please help in fixing this issue in iSH?
And of course let me know if I can help in any way :-).
Thanks a lot and keep the excellent work with iSH!
Kind regards, Maurice
** Easy steps to reproduce this bug on iSH v1.3.2 (Build 494)
echo hello >a apk add nodejs node -e "require('fs').copyFileSync('a','b')"
** Note
Having a non empty 'a' file is important because copying an empty file actually works
** Results on the defaut iSH alpine v3.14 with default minirootfs v3.14.3
node -e "require('fs').copyFileSync('a','b')" internal/fs/utils.js:332 throw err; ^
Error: EPERM: operation not permitted, copyfile 'a' -> 'b' at Object.copyFileSync (fs.js:2062:3) at [eval]:1:15 at Script.runInThisContext (vm.js:134:12) at Object.runInThisContext (vm.js:310:38) at internal/process/execution.js:81:19 at [eval]-wrapper:6:22 at evalScript (internal/process/execution.js:80:60) at internal/main/eval_string.js:27:3 { errno: -1, syscall: 'copyfile', code: 'EPERM', path: 'a', dest: 'b' }
node -v v14.21.3
** More expressive results on latest alpine v3.18 with minirootfs v3.18.2
node -e "require('fs').copyFileSync('a','b')" node:internal/fs/utils:351 throw err; ^

Node.js v20.3.1
** Results using previous alpine versions

minirootfs:
** Some variations if needed
node -e "require('fs').copyFileSync('a','b')" node -e "require('fs').copyFile('a','b',console.log)" node -e "require('fs').promises.copyFile('a','b')" node -e "require('fs').cpSync('a','b')" node -e "require('fs').cp('a','b',console.log)" node -e "require('fs').promises.cp('a','b')"
