Source-build CentOS fails: shell quoting bug in previously-source-built-sdk path

[lewing]

Source-build CentOS fails with shell quoting bug in previously-source-built-sdk path

Symptoms

The SB_CentOSStream10_Offline_PreviousSourceBuiltSdk_x64 job fails on the internal main branch builds with:

./build.sh: line 245: cd: /__w/_temp/previously-source-built-sdk': No such file or directory

Note the stray trailing single quote in the path. The build command shows the quoting issue:

sudo -E unshare -n ./build.sh --with-sdk '/__w/_temp/previously-source-built-sdk'\''

Affected Builds

• Build 2992036 (main, June 4)
• Build 2991361 (main, June 3)

Impact

This is a repeat failure on main, causing the source-build offline job to fail consistently.

We'll keep an eye on this but it's not consistent. It passed on a retry and another build.

@lewing our team usually does not work on issues inside the VMR so can you maybe drop the prodconsvcs alias from these?
