If we are interested in discussing this change, we need some more information for the discussion to be fruitful. Specifically, we need to know how the path limit is set and used in the Linux source code [0]. From there, we will be more able to evaluate the feasibility and impact of the change. This will also help us to understand why the limit exists. Perhaps the limitation is required by Linux across the full set of platforms (libc and filesystems) it aims to support, but not for the platforms supported by Guix. Finally, it will be helpful for the rest of guix-devel to understand why we'd want to make this change. So far, the path length limit=20 of 4096 characters seems long enough for us... [0] My understanding is that the PATH_MAX macro from limits.h sets a 4096 "character" limit. --zhXaljGHf11kAtnf Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEsFFZSPHn08G5gDigJkb6MLrKfwgFAlrvU1YACgkQJkb6MLrK fwhXwhAAnGaEcKVmAZ5SWNJb5eRGfKPfpgMCpwXSp1a3QFHYo1GYCoVw4ex5F2hn TNLQAXHfw9c0lh/S+vQPgzKHy67lPlP07QqX0mNiiP9oj17TyEBjq4PZh8teKrr3 B7MI3jC5DzbMTjYFrtZ/wGbPs611RpttkYaoMCuoZIVmUTVXsYgna2rVesy5vMJ6 Yyln0m1qCTYfcPbPzf2zu+BHIoo7t9WDpILnxVSCb/W4N9cnIs9MEOOrGZxYKu1X Yi1JDVZIqAHgmEIyD1DnjmEKwMH7ltj9ePcMF/+SEiyhqd1TKI2BGyanNiDq2qOV OlUTx33s2j8vJQjI+qkkvyfxVnPF1VRdDCKI3gepKNz9zZQfmbumBfBEsakC3EEv xbzupwLwTIRDquiCx40Jnh0w+iSa+yj3pG+q6OsGiHLQJr0GRvbICUqTEJn7xDLS hChJK8nI4x+BYhF9WD+SfgDGt+SUlO7fJwlTc96lmwaT7rTscmol/sZ7n8AlXk4a kFiy5auHi2XXc5cGoiiyVR5/o6NB/ArkkEswNHo8GVfYFN3FE1IUBheX1sAS/vST YQ6nzf3I1Ir6zt0au2r+kIMqyfeun7egeFfsaPRFQd4Ukuca0bVaCOKLvcRLn7tq rD6gGuLttF+Fnr1rftixgs0qekbAzQez40FxxKBcVLgpfjzIzew= =GHqq -----END PGP SIGNATURE----- --zhXaljGHf11kAtnf--
