[ Upstream commit ec336aa83162fe0f3d554baed2d4e2589b69ec6e ]
The backslash characters escaping '$' in the command to sed (intended to prevent it from interpreting '$' as "end-of-line") are currently being consumed by the Shell (where they mean that sh should not evaluate what follows '$' as a variable name). This means that
sed -e "/ $/d"
executes the script
/ $/d
instead of the intended
/ $/d
So escape twice in mksysmap any '$' that actually needs to reach sed escaped so that the backslash survives the Shell.
