[PATCH 1/2] boot: ignore all spaces between boot targets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Boot targets are split by space. strsep unlike strtok(_r) returns an
empty string for each pair of consecutive delimiters. Ignore this case.

Note that this changes behavior: previously both
	boot ''
	global.boot.default= boot

were identical to
	boot /env/boot

With this change, this is no longer the case.
